Can Distribution groups created in EOL in hybrid environment seen in Exchange On Premises address book?

It cannot be seen on-premises, as DirSync is one way only, from the AD to O365. So you have to create another object on-premises to represent the DG address. Generally speaking, any type of object should do, including mail contact, just set the targetaddress to point to the DG@tenant.onmicrosoft.com value.
I tried and this worked VasilMichev.
However does this treat your message as an external message, it is doing so to me. Do we have to add tenant.onmicrosoft.com as authoritative on premises exchange server. I already have tenant.mail.onmicrosoft.com added as authoritative during hybrid configuration.
Its possible but tricky and have some loophole Sai Gutta

Mansihsain- I see the links talk about Office 365 Groups, however I am looking at Distribution Groups/lists.
And also can on-premises users send emails to Distribution groups in Exchange Online, I receive a message hop count exceeded NDR
Thank you for your response.
